Step by step

1. 

   Check Deep sleeping apps

   Settings, Battery, Background usage limits. Samsung says apps in Deep sleeping apps never run in the background. On our Galaxy A57 the number next to it was 7.

   Watch these steps Done

2. 

   Take the app out of the list

   Open Deep sleeping apps (and Sleeping apps) and find the late app. Samsung's notifications page says to touch and hold the app and tap Remove. Its sleeping apps page says to tap the three dots, then Remove apps. On our Galaxy A57 with One UI 8.5 that menu item reads just Remove.

   Done

3. 

   Add it to Never auto sleeping apps

   Apps in this list are never put to sleep. Add every app whose messages must arrive on time. Samsung's sleeping apps page calls it Never sleeping apps; on our Galaxy A57 with One UI 8.5 the row is Never auto sleeping apps, with 0 apps in it.

   Done

4. 

   Or stop putting apps to sleep

   Samsung says Put unused apps to sleep sends apps you have not used for a while to sleep automatically. Switching it off helps every app, at some cost to battery life. It was on on our Galaxy A57.

   Done

5. 

   Turn off Power saving

   Samsung says Power saving reduces background activity. Swipe down from the top right and tap Power saving to turn it off. On our Galaxy A57 it was off. The quick panel takes its colour from the wallpaper, so on our phone it is lilac grey even in Dark mode.

   Done

6. 

   Check the app's notification settings

   Settings, Notifications, App notifications, then the app. Allow notifications must be on, and the Lock screen and Notification pop-up boxes must be ticked if you want to see them there.

   Done
